ERROR: :81: native calls disabledDpget and dpsave both work as expected.

Does the error refer to CHDK (on the camera) build time config option OPT_FORCE_LUA_CALL_NATIVE ? If yes, the warning inside buildconf.inc mentions "permanently enable native calls." Does permanent mean irreversibly set forever in the camera? Or simply that I have to rebuild CHDK with option=0 to turn it off?
